MACHINE FOR REMOVING AND REPLACING METAL PARTS OF TRAIN-PIPE COUPLINGS.

Specification of Letters Patent.

Patented Jan. 8, 1918.

Original application filed October 23, 1916, Serial No. 127,151. Divided and this application filed July 25,

- 1917. Serial No. 182,752.

To all whom it may concern:

Be it known that we, WILLIAM D. FAIDLEY, J r., residing at Clifton Forge, Alleghany county, Virginia, JOHN W. Mourns, residing at Iron Gate, Alleghany county, Virginia, and SAMUEL A. PATTERSON, residing at Clifton Forge, Alleghany county, Virginia, citizens of the United States, have invented certain new and useful Improvements in Machines for Removing and Replacing Metal Parts of Train-Pipe Couplings, of which the following is a specification.

This invention relates to mechanism for detaching the metal parts of worn out train pipe couplings, especially the coupling heads, nipples and clamping bands carried by the opposite ends of the hose sections comprising such train pipe or air brake couplings, and for applying such metal parts to new hose sections. Heretofore when a hose section has become so worn as to be of no further use, the whole coupling has been discarded, although the metal coupling head, nipple and clamping bands are by no means unfit for further service. It is the aim of this invention to provide a machine for removing such metal parts from the old hose sections and for attaching them to new hose sections so that they may be again utilized, and the present invention is the provision of means principally for the removal of the clamping bands or rings from the worn out couplings or hose sections in such manner that said clamps or rings are preserved and may be used on the new couplings and great expense thereby saved both in labor and material.

The coupling head and nipple are fastened to the opposite ends of the hose section by clamping bands or rings having spaced outwardly turned flanges at their ends secured together by bolts bridging the space between said flanges. These clamping bands or rings must be removed before the coupling head and nipple can be separated from the end portions of the hose section, and the machine embodying the invention is equipped with means for doing this as the first step in the removal of the metal parts of the coupling. Means are also provided for holding the hose section while the coupling head and nipple are either withdrawn therefrom or applied thereto, and also for the complete removal of the clamping bands.

The invention will be first hereinafter described in connection with the accompanying drawings, which constitute part of this specification, and then more specifically defined at the end of the description, the present application being a division of our application filed October 23, 1916, Ser. No. 127151.

In the accompanying drawings, wherein similar reference characters are used to designate corresponding parts throughout the several views:

Figure 1 is a side elevation of a machine constructed substantially in accordance with one form of the present invention,

Fig. 2 is a plan view of the same,

Fig. 3 is a detailed plan view of the means for cutting the bolts which hold the clamp- 111;; band on the coupling,

Fig. 4: is a side view of the same, and

Fig. 5 is a detail perspective view of one form of tool for removing the loosened or spread clamping bands from the hose sections.

A table 1, which carries certain parts of the machine is mounted upon suitable supports 2 and 3 at opposite ends thereof, the supports 2 at one end extending up through the table, as at 4;, and supporting the pivot 5 of a lever 6 for operating the reciprocating knife 7 which is used for cutting the bolts 8' holding the clamping bands 9 around the hose sections. Said lever 6 is operatedby a bell-crank lever S pivoted at 9 between a pair of longitudinal bars 10 arranged below the table 1, one end of said bell crank lever being connected to the lever 6 by a pitman 11 while the other end of said lever S is connected to the piston rod 12 of a compressed air cylinder 13 located on a platform 14: at the base of the table. Any suitable means (not shown) may be employed for controlling the reciprocating movement of the piston rod 12 for moving the knife 7 through the instrumentality of the bell crank lever 8 pitman 11 and lever 6. I

At one end of the knife 7 there is a depending guide 15 working in a slot 16 in the table. Another slot 17 enters from one side of the table and terminates adjacent the knife, and into this slot 17 the hose 52 is introduced, as shown in Fig. 3, when the bolt 8 is to be cut. WVhen the hose is in position in the slot 17as shown in this figure,

the clamping band 9 is arranged above the top surface of the table and the middle portion'of the bolt is "disposed below the knife, so that when said knifedescendsit will 'cut through said middle portion of thebolt thus releasing the end portions 'or flanges 18 of the clamping band from one another. v

During the cutting operation the bolt 8 issup'port'ed :upon beveled lug 19 projecting above the top surface of the table -1 and having a vertical face 20 arranged substantially in vertical alinement-with the flatsi-de of the knife 7. The opposite face of 'the lug 19 is inclined as at 21, Fig. 6. *Thexbolt 8 also rests upon a beveled laterally extending lug 22 ona slidin member 23-fitted in a recess in the table'l and-normally held in the positionsho wn in Figs. 3 and 4 by a spring 24. When the knife descends its beveled edge, after-passing through-the bolt 8, enters between the "lugs 19 and 22 and forces thesliding member 23 away-from the fixed lug 21, thereby spreading the flanges 18 on theclampin'g ring' 9 to some extent. As thekni'fe completes its downward stroke the head 2,5-comes in contact with the flanges 18 and forces them still farther apart as they are moved down along the inclined face 7 21 of'the lug 19 and the correspondingly inclined opposite face 26 ofthe lu-g'22. After this operation the clamping -band9 will be loose enough" to be readily removed when the coupling head and nipples. are taken oif by them'ec'hanism described and claimed in our application before mentioned, Ser. No. 127151. After being removed the clamping bandfis in condition to beused again for holding a nipple or coupling-head on a new hose section.

One former mechanism for entirely removing the clamping band or ring fro'mthe hose secaon, as well as removing the coupling heads and nipples is fullydescribed andclaimed in said application Ser. No. 127151, and so fa r'as the mechanism for removing "the coupling heads and nipples is "concerned-forms no art of the resent a plication.

, 'Aft'er'the bolt has been severed and the clamping bands or rings partially opened or spread'as 'above set forth, said-hose'section is then "placed across the stationary jaw 27 "of a holdin =clamp arranged on the table 1,. and the supplemental"movablethem ber '28 of said clamp is forced .down upon it by means of compressed air apparatus i neluding a cylinderl29 supported on the back ofith'e lila'chine, a piston rodj30 working in said cylinder, an intermediately pivoted lever ,31'connected at one end to's'aid piston rod, and a link '32 connected to the other end of 'th'e lever 31 "and to the movable jaw 28; It will be-understood that -any suitable means (not shown) be employed for controlling this compressed "air apparatus.

At one side of the clamping jaws 27 and 28 a sliding block 33 is mounted on guides 34 to be moved toward and away from said clamping jaws. The movement of said block 33 is effected by a lever 35 .pivoted at 36 between the bars 10,a'link 37 connected at one and connected to the other end of the link 40, and a piston rod 43-working in a compressed air cylinder 44 and connected to the lever 41, as clearly illustrated in Fig.1.

At the other side of'the' clamping jaws 27 and 28 a block 45 is mounted to 'sli'de -on guides 46 toward and awayfrom said jaws, and said block 45 is "reciprocated *by means of a lever 47 pivoted at 48 between the bars 10, and a link 49 connectedat one'end to thelever'47 and at the o'ther'end to the lever 38. From the arrangement'oflevers shown and described, "it will be seen that the outward movement of the piston rod 43 will cause the blocks 33 and 45 to move inopposite directions away from the clamping jaws 27 and 28, while the reverse movement of the piston rod 43-will advance the blocks 33 and 45 toward'said'clamping jaws. The'block 45'carries a tool 50- ad'apted t enter the nipple on the adjacent'end of the hose section on the advance movement of said block 45. The specific form of tool is described and claimed in the above inen tioned application Serial No. 127151, and inasmuch as it forms no part of the'present invention further description thereof is deemed unnecessary. V 7

After thetool "50 is introduced into the end of the-hose sectionpast'the nipple means 7 are provided for grasping the couplings and nipple-and forcibly removingj'them on the return movement of the tool.

Tools are provided for removing the; parsaid hingedportion. The hinged portion 81 is of angular formation so as to raise it above the tools 50 and 69, and is notchedjat 81 to avoid interfering with the hand -le-' ver58; The lingers 83 are designed teembrace the hose section 58. The fingers-83 are designed to embracethe "hose sect-ion 52 and engage the clamping bands 9, which.

have been loosened or spread as already eX- plained, whereby said clamping bands are removed froi nfthe hose section simultaneously with the removal or the nipple andcoupling head when the blocks-33 and'45 are each of the removed away from each other. The fingers 83 may be adjusted, as suggested at 8%, for fitting different sizes of hose sections.

The operation of the machine will be obvious and apparent from the foregoing description and detail statement of such operation is unnecessary. The worn out hose section having been properly placed on the table 1 with the bolt 8" supported upon the beveled lug 19 and the knife with its operating mechanism having been operated to sever the bolt and spread the clamping bands or ring slightly said hose section with the clamping bands loosely secured thereto is then placed in the clamp 27 and the tool shown in Fig having been properly located with reference to said clamping bands the clamping bands are removed on the return movement of the blocks 33 and at the same time that the couplings and nipples are removed.
